REGISTERING-PADLOCK.

SPECIFICATION forming part of Letters Patent No. 427,284, dated May 6, 1890.

Application filed May 24, 1889. Serial No. 311,942. (No model.)

To all whom it may concern:-

Be it known that I, RANDOLPH G. WARD, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Registering-Padlocks, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a section through the body of the lock, showingits mechanism entirely within one-half of the shell or case of the lock. Fig. 2 is the outside case of the lock, shown open with the key withdrawn. Fig. 3 is a crosssection through the middle of the lock on lines x 00, showing the key inserted. Fig. 4 shows an open extended plan or view of the shackles or bolts in the position indicated in Fig. 1. Fig. 5 is the key. Fig. 6 shows upon an enlarged scale the two registering ratcheted indicators. (See also Fig. 1.)

The purpose and object of my invention are to furnish a good and efficient lock which shall be operated by a key of other than the conventional types, which key shall be provided with a number of simple but co-essential combinations, and also that there shall be provided within the look a simple but unerringly-accurate registering or indicating device having numerous combinations whereby it may be determined if the lock shall have been opened without proper knowledge or authority. I accomplish these ends by means of the mechanism shown in the accompanying sheet of illustrations, in which like letters refer to like parts throughout the several figures, in which- A A are the two halves of the shell or case of the lock, being provided with the slot at through its peripheral edge'for admitting the staple behind the bolts or shackles, the cored boss a for insertion. of key, and the recesses a a a a and a for the accommodation of the various mechanisms shown and hereinafter more fully described in detail.

B B are the two reciprocating or oppositelythrusting shackles or bolts, in which I) represents-racks or gears by means of which the opposite thrusting or reciprocating is accomplished through a simple turn of the key.

I) are slots into which the pawls drop, by which bolts are secured when locked.

b are slots within which the ratchet-pawl 19 (see Fig. 1,) which works the registering or indicating devices, operates.

b are the half-boxed ends of-the bolts 0r shackles, which when thrust together form the shackle or bolt proper, Figs. 4, 3, and 1.

O is the main locking device, provided with the pawls c, actuated constantly in one way by the spring 0.

D is the secondary locking device, in which 01 d are the stop-pawls, and d the actuatingspring.

E is the numeral-ratcheted indicator or registering-wheel, provided with an even number (or odd, as desired) of ratchets, each of which is numbered.

F is the alphabetical indicator or registering-wheel, provided with an odd number (or even, if desired)'of ratchets, upon each of which is a letter or character, Fig. 6.

G is the key, provided with a solid turned shank g, a geared projection g, a reduced shouldered secondary shank g and the reduced bit g provided with the taper g.

The operation of my lock is as follows: The key is inserted through the core or key-hole a. The tapered bit passes through the main locking device 0 and separates from below the same the stop-pawls d. The shoulder g of the key then acts upon the locking device 0, thrusting it inward and withdrawing the pawls c from the slots 1) of the bolts B. The key is then turned, and the gears g, by means of the rack 12, cause the bolts to be withdrawn in opposite directions, causing the lock to open and, by means of the pawls I), operate the indicators E and F one notch, which is held by the pawls e and f, respectively, and indicated through the face A, as shown in Fig. 2. It will be seen that as one of these indicators has even and the other odd notches it will require as many complete revolutions of these indicators as there are notches in the wheel containing the greatest number before the same combination will reappear, thus giving a large number of combinations with a very simple device.

drawal of the key causes the device to look.

What I claim is- 1. In a lock, the combination of two bolts simultaneously but oppositely actuated by a The opposite turn and with ously-reciprocating thrust and draw, the combination of the main locking device 0, the

pawls c, the spring 0, and the slots 19, for look ing said bolts.

3. In a lock having two simultaneously but oppositely actuated bolts, the combination of the locking device 0 with the stop-pawls d, actuated by the spring d and provided upon their inner sides with projections, as shown, and for the purpose described.

4. In a look, a multiple registering device consisting of two separated non meshing notched or ratcheted wheels, one upon each side of the center, one having an even and the other an odd number of notches simultaneously actuated bya motive device and bearing on their faces numerals, letters, or characters forregistering purposes.

5. In a lock having two simultaneously but oppositely actuated bolts, the combination of notched rotary registering devices with pawls situated in and actuated by said bolts upon said registering devices, substantially as shown and described.

6. The combination, with a lock, substantially as shown and described, of a key having a shank of a larger diameter than the other parts of the bit, with a gear or pinion thereon having a secondary shouldered shank of smaller diameter, and a still smaller bit with a tapered point thereto, substantially as and for the purposes described.

In testimony whereof I have affixed my signature in presence of two Witnesses.

RANDOLPH G. WARD.
